CAMBRIDGE, Wis. (AP) -- The mother of NASCAR driver Matt Kenseth has died.

An obituary from a Cambridge funeral home and Kenseth's fan website say Nicola "Nicki" Sue Kenseth battled Alzheimer's disease and died Tuesday at age 63 at Oak Park Place in Cottage Grove.

A funeral service is scheduled Friday at Willerup Methodist Church in Cambridge. She is survived by her husband, Roy, her children, Kelley and Matt, and five grandchildren.

Matt Kenseth grew up in Cambridge and won the Daytona 500 in 2009.
